Here is the list of domains from the original doctor beets post linked in the this story to block on your router to stop this:

ad.lgappstv.com

yumenetworks.com

smartclip.net

smartclip.com

smartshare.lgtvsdp.com

ibis.lgappstv.com

FWIW, all of these are in Dan Pollocks ad blocking hosts list:

http://someonewhocares.org/hosts/

On my network, I use the following script to convert the hosts file he provides into an unbound config file which I include from my main unbound config, using this script:

https://github.com/jodrell/unbound-block-hosts

This provides ad blocking for my entire network, including my smart tv.

Thanks, was looking for a list like this. I've blocked them all via DNS, hopefully doesn't break anything too important.

What sort of communication between your TV and these domains would you feel is important?

I don't specifically know the services the TV expects from those domains but:

You may want to receive software updates for the TV.

You may also want to access services that the are launched by the LG apps. Those services may only run correctly when the appropriate pre-roll advertising (quite possibly from Smartclip) are allowed to play.

Why not just blocking traffic originating from the device in question?

That's okay for some, but many people use the built in apps for Netflix, Livefilm etc.
